MOT Type 1 Calculator

MOT Type 1 Calculator

Our MOT Type 1 calculator can be used to get an estimate for most aggregate materials.

Please note: Our MOT Type 1 calculator calculates by tonnage, and the calculations are approximate. The exact conversion will depend on a few other factors, such as the bulk density of aggregate, the method and degree of compaction, and more.

Composition

MOT Type 1 is typically comprised of aggregates from:

These materials are crushed to a maximum size of 40mm to dust, resulting in a well-graded aggregate with excellent compaction properties and load-bearing strengths.

Applications

MOT Type 1 is essential for applications needing certified material and ideal for applications especially where a stable and durable sub-base is required, such as:

  • Highways
  • Car parks
  • Footpaths
  • Driveways
  • Hard standings
  • Building sub-bases

Frequently Asked Questions

What is MOT Type 1?

MOT Type 1 is a sub-base material composed of crushed stone such as Granite, Basalt, Gritstone, or Carboniferous Limestone, depending on its source. The aggregate size typically ranges from 40mm down to dust particles.

Is MOT Type 1 suitable for driveway sub-bases?

Yes, MOT Type 1 is an excellent choice for driveway sub-bases when the final surface is either gravel or tarmac. However, for block-paved driveways, a more permeable sub-base, such as MOT Type 3, may be necessary to meet Sustainable Urban Drainage System (SUDS) regulations.

What Are the Specifications for MOT Type 1?

MOT Type 1 is produced in accordance with the Specification for Highways Works Clause 803, which ensures a consistent product designed to withstand frost heave.

How Do I Calculate the Quantity of MOT Type 1 Required?

For driveway sub-bases intended for car traffic, MOT Type 1 should be applied at a depth of 150mm. Heavier loads might necessitate a deeper sub-base, which could require calculations by a structural engineer. Generally, a depth of 75mm is suitable for footpaths, while patio sub-bases should be 100mm deep. We recommend you use our aggregate calculator on this page. Simply select ‘Type 1 MOT and enter your measurements in meters for length and width and in millimetres for depth to calculate the quantity of MOT Type 1 your project requires.

How Do I Install MOT Type 1?

To install MOT Type 1 effectively, start by evenly spreading the material with a shovel. Compacting MOT Type 1 in layers using a vibrating roller or whacker plate is essential to ensure a stable surface and prevent future settling. For your convenience, Bullimores Plant Hire offers the necessary equipment to help you achieve a professional finish.

For optimal results, aim for recommended installation depths of 150mm for driveways, 75mm for paths, and 100mm for patios. This approach will help create a durable and long-lasting foundation.

Is MOT Type 1 Free Draining?

MOT Type 1 does facilitate water passage, though at a slower rate compared to other products like MOT Type 3.
